When Dark Energy turned on
The record of baryon acoustic oscillations helps astronomers to retrace the history of the expanding universe.

Graphic by Zosia Rostomian.The Sloan Digital Sky Survey (SDSS-III) today announced the most accurate measurements yet of the distances to galaxies in the faraway universe, giving an unprecedented look at the time when the universe first began to accelerate. From different perspectives six publications, which have been published online now, address the question of “Dark Energy“, the unknown force that drives our Universe apart.

Sebastian Nuza of the Leibniz Institute for Astrophysics Potsdam (AIP) is among the co-authors. His specialization are numerical simulations of cosmological structure formation and predictions of the clustering of galaxies. All published results together allow for the most complete view of the distant Universe and are an important step towards understanding what drives its expansion.
